ASTM Grade LC2-1 Steel vs. EN 1.4922 Stainless Steel

Both ASTM grade LC2-1 steel and EN 1.4922 stainless steel are iron alloys. Both are furnished in the normalized and tempered condition. They have 89% of their average alloy composition in common. There are 30 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is ASTM grade LC2-1 steel and the bottom bar is EN 1.4922 stainless steel.
